Petrogenesis of Cenozoic basalts in central-eastern China: Constraints from Re–Os and PGE geochemistry

We present Re–Os and PGE (platinum group elements), together with major–, trace–element and Sr–Nd isotope data, to further constrain the petrogenesis for the Cenozoic basalts in central-eastern China. The basalts include low-Ca alkali, high-Ca alkali and tholeiitic varieties. Most low-Ca alkali basalts have unradiogenic 187Os/188Os (mostly < 0.14), flat chondrite-normalized PGE patterns and depleted Sr–Nd isotopic compositions, indicating that...
